Vvhen hot solutions evaporate in vacuo in a continuous operation forthepurpose of cooling-condensing or separating salts, the

condensates are usual y withdrawn by means of a jet pump. If a water jetpump is used as the jet pump; then the quantity of Water to be used inoperation must be large in order to carry away and volatilize the vaporswhich are produced. 1

The subject of the present invention resides in effecting the removalofthe condensate with at the most so much water as is necessary for thecondensation, as the condensates before passing into the jet pump, arecondensed by a condenser of usual construction by the water of the jetpump. In this connection it is immaterial for the carrying out of theinvention Whether the pump is driven by the cooling water which isflowing in or flowing out.

The invention is particularly applicable for the separation of epsomsalts (G'auber salt) and potassium salts. For the purpose of obtaining ahigh degree of vacuumv 2 and therefore alow cooling temperature thecondenser or the jet pump can also be operated with" cooled Water orcooled brine.

In the drawing is shown by way of ex ample a device for carrying out theinven- I claim as new and desire to secure byiLettors Patentis: a 1. :Incombination, a'condenser, and a jet pump connected to said-"condenserfor removing condensate therefrom, said jet pump throuqh said condenser.v
